Error with ncei_2roms

[diego_b]

Good afternoon,
i'm trying to create surface forcing for my ROMS simulation, but when i try to run the ncei_2roms.m script, after providing it my grid (created with Grid Builder in nc format), i obtain this output

>> ncei_2roms
## Creating romsforc_NARR_Sandy2012.nc...

Error using matlab.internal.imagesci.netcdflib
The NetCDF library encountered an error during execution of 'open' function -

Could you please help me out through it? Let me know if i can provide other useful information.

Hi diego,

maybe the script can't find the nc file from the ncei/noaa thredds, cmiiw.
In the ncei_2roms.m file, the web address of the ncei noaa data source is provided, You can see if the data you want is in thredds or not.

Many NCEI services hosted in Asheville, NC, are down until further notice due to the impacts of hurricane Helene.

Hurricane Helene made landfall Friday September 27th and proceeded to
move inland toward the Blue Ridge Mountain area and more specifically
Asheville, NC. Asheville, NC is home to NOAA's National Centers for
Environmental Information (NCEI) and many other NOAA services
including NODD's Data Broker which moves a variety of datasets from
on-prem to the cloud. The Asheville area has experienced significant
and catastrophic damage from the storm that has left roadways washed
out, areas impassible, and taken down critical infrastructure like
power, internet, and cell service. This is affecting our ability to
deliver data to the cloud and ultimately our customers. Internet and
power are essential for our ability to run the necessary
infrastructure to deliver data. Once that is restored we will work to
restore our data feeds. We are sorry for any inconvenience this may be
causing.

Thanks,
